HAY-CARRIER.

Specification of Letters Patent.

Patented. Nov.-13, 1906.

Application filed May 14, 1906. Serial No. 316,835.

To all whom, it may concern:

Be it known that I, Ln ROY WrLLoUR, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and'useful Improvements in Hay-Carriers, of which the following is a specification.

This invention relates to new and useful movable in proximity to the ceiling thereof.

. an end view thereof.

The primary object of the invention is to provide simple and inexpensive means for accomplishing the above-named function.

A further object of the invention is to provide means for automatically locking the carrier at a selected position and for automatically releasing the load from the carrier at a selected position.

The detailed construction will appear in the course of the following description, in which reference is had to the accompanying drawings, forming a part of this specification, like characters designating like parts throughout the several views, wherein Figure 1 is a side elevation of a transferring device constructed in accordance with my invention and showing its'application to a barn or other stationary structure. Fig. 2 is Fig. 3 is a central vertical section of a carriage-hanger embodied as a component element of the present in vention. Fig. 4 is a bottom plan view of a section of the carriage, illustrating the detailed construction of the locking device therefor; and Fig. 5 is a transverse section of a joist, illustrating in end elevation the mode of securing the above-mentioned hanger thereto.

In the practical embodiment of my invention the letter A designates the roof of a barn which is provided with spaced parallel rafters B, arranged transversely thereof. Depending from the several rafters are hangers 1,

. which are constituted of a box-like structure,

ranged in pairs on each side of the hangers at the corners thereof and by which said hangers depend from said rafters. Adjustably mounted within the several hangers 1 are depending yokes 5 of substantial U shape, with an upwardly-extending threaded stud 6 projecting through the slot 3 and carrying an adjusting-nut 7, resting upon the upper wall of the hanger 1 and by which yoke 5 is adjusted vertically with relation to said hanger. Horizontal adjustment of said yoke in either direction is effected by means of adjustingscrews 8,"threaded through each end of the hanger 1 and bearing against the adjacent sides of the yoke5. The depending legs of said yoke carry at their lower ends trackpulleys 9, rotatably mounted upon supporting stub-shafts and arranged in spaced rela tion and in parallel planes. Owing to the various adjusting elements, any inequalities which may exist in the roof may be compensated for by the proper adjustment of the yoke with relation to the hanger. A carriage 10 moves upon the rollers 9 in the space between the depending legs of the yoke 5. This carriage 10 may be of any desired form and in its preferred embodiment is in the form of an'I-beam, provided at the edges of its flanges with'inturned portions 11, which serve as treads and engage the rollers 9. The carriage 10 is provided with suitable mechanism for -suspending a' load therefrom, of which an advantageous construction is shown comprising depending sheaves 12 and 13, carried by said carriage. The sheave 12 is idle andhas rigid connection with one end of a rope 14, trained over the sheave 13 and carrying at its free end a handle 15. A pulley 16 is supported upon the rope 14 and is j ournaled in a frame 17, from which depends a sling or hook 18 for supporting the load and which serves as a counterbalance for the pulley 16.

Along a portion of its length the I-bearn forming the carriage 10 is provided with a transverse slot 20, and on each side of said slot apertured upstanding lugs 21 are formed, through which pass detents 22, formed with adjacent angular inner ends 23, the free ends of said detents passing, as at 24, through openings provided therefor in the sides of the Lbeam. The detents 22 are forced outwardly in opposite directions, so that the inner ends thereof closely approach one another by expansive coil-springs 25, surrounding the same and interposed between lIl lugs 21 and the adjacent sides of the I-beam. For engagement with the detents '22 the frame 17 is provided with an upward eXtension terminating in a nose 26 of substantial inverted-V shape and beneath said nose with a shoulder 27, having the same contour.

The legs of the yokes 5 are each provided with apertures 5, and adjacent to said apertures are cam-faced shoes 28, arranged eX- teriorly' of said legs and projecting therebeyond on each side, said shoes being formed with apertures 28, registering With said apertures 5 The hangers 1, assembled in the manner described, are braced by plates 29, arranged transversely between the arms 4 and secured in any desired manner to the rafters B.

In practical use an I-beam, forming the carriage 10, of requisite length is employed, which is moved from one section of the structure or building to another. The load to be transferred is positioned upon the suspensionhooks 18 and is raised by pulling the cord 14. In this operation the nose 26 passes through the slot 20 in the carriage 10 and enters be tween the ends 23 of the detents 22, spreading them apart, and the. shoulder 27, engaging said detents, maintains them in this position, so that the load is positively supported by the nose 26, resting upon the ends 23 of said detents. Prior to the above operation the carriage 10 is locked at some selected rafter by the detents 22, which project through the openings in the legs of the yoke 5. The operation of engaging nose 26 with detents 22 23, above described, disengages said detents from said openings and permits of the movement of the carriage by any desired means to a selected rafter, The yoke 5 at the selected rafter will be provided on each leg thereof with the shoes 28, and in the for ward movement of the carriage 10 the end of the detents 22 will engage said shoes, whereby the free ends 23 of said detents will be forced apart, thereby permitting the nose 27 to drop by gravity in order that the load maybe detached from the suspensionhooks. The de-v tents 22 are moved by the cam-shoes 28 until they are in alinement with the registering openings in the legs of the yoke 5 and in said shoes, at which time the springs 25 will act to move the detents 22, so that their free ends will pass through the openings, and thus lock the carriage 10 at the selected position. The operation detailed at the beginning of the paragraph is then repeated, and so on ad infinitum.

While the elements herein shown and described are well adapted to serve the functions set forth, it is obvious that various minor changes may be made in. the proportions, shape, and arrangement of the several parts without departing from the spirit and scope of my invention as defined in the appended claims.

Having fully described my invention, I claim 1. A transferring device comprising supporting alined hangers, a beam suspended from two or'more of said hangers and movable with relation thereto, -a vertically-movable load-supporting means carried by said beam, means carried by said beamfor engagement with said hangers to lock said beam adjacent to a selected hanger and means carried by said load-supporting means for actuating said locking means to release said beam and permit of the further movement thereof.

2. A transferring device comprising supporting alined hangers, a beam suspended from two or more of said hangers and longitudinally movable with relation thereto, load-supporting means carried by said beam and vertically movable with relation thereto, latch members provided upon said beam, keepers provided upon selected ones of said hangers and designed to receive said latch members in looking engagement and means carried by said load-supporting means for disengaging said latch members from said keepers, and permitting of the further longitudinal movement of said beam.

3. A transferring device comprising sup porting alined hangers, a beam suspended from'two or more of said hangers and longitudinally movable with relation thereto, load-supporting means carried by said beam and vertically movable with relation thereto, spring-pressed latch members provided upon said beam, curved apertured keepers provided upon selected ones of saidliangers and designed to receive said latch members in locking engagement, means provided upon said load-supporting means for tripping and maintaining said latch members out of engagement with said keepers and for engaging said latch members as suspending devices for said load-supporting means, said latch mem bers in the continued movement of said beam being designed to engage said keepers as cams and to be moved thereby so as to release said load-supporting means.

In testimony whereof I affix my signature in presence of two witnesses.

LE ROY WILLOUR.
